Yes, but it didn't take long to figure out that there were better ways to do things than the coonass way.
Today the development of new oil field equipment and technology has migrated from USA to Norway, with more Norwegians working in the industry in USA than Americans in Norway. (I'm not talking about in the GoM only)
Top end drilling and Subsea equipment is now developed and produced in Kristiansand, drilling & production technology development in Stavanger area, Seismic in Bergen and Marine equipment, shipbuilding and ship design concentrated around Aalesund. All supported by advanced research at NTNU and SINTEF in Trondheim.
Oslo Stock Exchange is one of the main sources of finance for the industry and many Norwegian and foreign owned companies in the worldwide Offshore and Shipping industries are listed there.
Norwegian Banks and Insurance companies are also heavily involved in the industry internationally, incl. in USA.
That is called free market force at work. "If you snooze you loose".
